Abstract
The invention discloses a kind of method for reducing milk cow discharge of methane, this method is that 10~50g active dry yeast is fed on the basis of basal diet.Wherein the viable count of every gram of active dry yeast is greater than 20,000,000,000, and living cell rate is greater than 60%.The milk cow is preferably holstein cow.The experimental results showed that not only its 4% fat corrected milk(FCM) improves 3%~8% after milk cow feeding active dry yeast, but also the methane emission of milk cow reduces 8%~20%.
Description
Technical field
The present invention relates to a kind of methods for reducing milk cow discharge of methane.
Background technique
In the factor for influencing Global Emissions of Greenhouse Gas, animal husbandry discharge of methane extensive concern.Global warming gas row
It puts the greenhouse gases that middle animal-breeding generates and accounts for 51%, the methane of animal-breeding discharge accounts for 37%, the discharge of ruminant gastrointestinal tract
CH4 accounts for about 19%.Since the half-life period of methane only has 8 years, and the half-life period of carbon dioxide is at least 100 years, calculates according to such
If, the greenhouse effects of methane are 72 times of carbon dioxide.Therefore, the discharge of methane has become current quarter in Animal husbandry production
Slow problem is not allowed.
It is accompanied by the loss of energy during methane discharge of ruminant, accounts about the 2%~12% of fodder energy, reduces anti-
Hay animal discharge of methane can not only alleviate greenhouse effects, and can reduce fodder energy loss, improve food utilization efficiency.
In recent years, domestic and foreign scholars continuously attempt to solve the method for this critical issue.By in ruminant
Add plant extracts, organic acid, ionophore, microorganism fodder etc. reduces discharge of methane.
Summary of the invention
The technical problem to be solved by the present invention is to overcome defects in the prior art, provide a kind of reduction milk cow discharge of methane
Method.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
A method of milk cow discharge of methane being reduced, the dry ferment of 10~50g of feeding activity on the basis of method is in basal diet
It is female.
Further, the viable count of every gram of active dry yeast is greater than 20,000,000,000, and living cell rate is greater than 60%.
Further, the milk cow is holstein cow.
Active dry yeast does not have any residual as a kind of natural green additive, to animal productiong.Cow feeding activity
Dry ferment can stablize rumen ph, promote fiber hydrolization, improve food utilization efficiency, improve the output of milk.
Currently, related yeast product, to ruminant production performance, the research of lumen fermentation has had a large amount of reports, still
Active dry yeast has not been reported for methane emission reduction.Greenhouse effect will be effectively relieved for milk cow methane emission reduction in active dry yeast
It answers, and food utilization efficiency can be significantly improved.
The beneficial effects obtained by the present invention are as follows being: to not only its 4% fat corrected milk(FCM) improves 3% after milk cow feeding active dry yeast
~8%, and the methane emission of milk cow reduces 8%~20%.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described, it should be understood that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
Embodiment
Select 60 body conditions good, lactation stage, parity, the average daily output of milk and weight are close, and genetic constitution is substantially similar
Holstein cow.It is randomly divided into 4 groups, every group 15.Wherein control group fed basal diet (pasture milk cow fully mixed diet), II
Group, III group and IV group add 10g, 20g, 30g active dry yeast (every daily), experimental period on the basis of basal diet respectively
90 days.The collection of methane is carried out in the first three days of off-test, every group is selected 3 cow heads installation gas collector, daily
For 24 hours, for three days on end.It sends the gas collected daily back to use for laboratory gas chromatograph to be measured, finally counts discharge of methane
Amount.
The results showed that
1), 4% fat corrected milk(FCM) of active dry yeast addition group milk cow improves 3%~8%；
2), the methane emission of active dry yeast addition group milk cow reduces 8%~20%.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
